CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 10/610,715 filed Jun. 30, 2003, the contents of which are incorporated by reference herein in their entirety.

BACKGROUND OF THE INVENTION

The present disclosure relates generally to the analysis of automatic line insulation testing data and in particular, to a method of facilitating the retrieval, organization and analysis of automatic line insulation testing data.

A typical regional telephone company central office, or wire center, houses a telephone switch to connect telephone calls between two or more parties. A main distribution frame (MDF) frame includes a row of jumpers to connect the switch wires to cable pairs from outside of the central office. Some cables utilize paper as insulation between the wires in the cable. Air compressors, located in the central office, are utilized to minimize the amount of water in the cables. When a cable gets nicked, the paper inside the cable may get wet and cause a short in the cable. It may be necessary to deploy a technician to fix the cable depending on factors such as the number of shorts in a particular cable. In some cases, such as when there is only one short in the cable, the paper may be dry once the technician gets to the cable to repair it. Sending a technician to repair a problem that was corrected should be avoided and technicians should be sent to repair cables that need technician action. One way to determine if a repair package should be built to send a technician to correct a problem is to have criteria such as: only build a repair package if there are more than three shorts, or crossings, of more than twenty volts in a twenty-five pair complement; and if there is only a two volt cross in a cable pair then do not build a repair package as the paper within the cable will probably be dry once the technician gets there. Any criteria may be used to determine when to build a repair package and the criteria may be varied or modified based on experience (e.g., in general or in a particular geographic location).

Currently, many regional telephone companies utilized an off-the-shelf computer product called Predictor to compile morning reports detailing automatic line insulation testing (ALIT) exceptions. ALIT is performed nightly by equipment that sequentially tests lines in the central office for battery crosses and grounds. The Predictor reports that include the results of all the tests, including good cables and cables with battery crosses and grounds, are sent to a printer. The Predictor report for each state (e.g., Tennessee) requires about one box of paper each night. Each morning maintenance administrators (MAs) analyze the reports and build Predictor patterns so that the technicians in the field may correct the problems identified by the tests. The MAs must sift through a box or more of paper each morning to find the failures, or exceptions, that need to be fixed. This practice may be cumbersome for the MA and because it is manual, may be error prone. Also, it may take all morning for the MA to sort through a particular portion of the Predictor report, with repair packages not being built until the afternoon. In addition, the current process does not produce back-up information for determining what information was presented to the MA when a decision to build a repair package was made.

DETAILED DESCRIPTION OF THE INVENTION

A method for analyzing automatic line insulation testing (ALIT) data is presented. The method identifies exceptions that need to be handled without going through the paper report. When an MA gets to work in the morning the ALIT information has already been processed and stored in an ALIT database. In an exemplary embodiment of the present invention, the MA logs on to a computer system and selects a district to be analyzed. The MA then views a list of the exception counts by wire center on the computer screen. The report automatically excludes exceptions that have already been addressed by repair packages. The MA may then select a wire center to drill down to the details of the exceptions for the wire center. The exceptions for each cable are grouped together and are color coded to indicate that the exceptions pertain to the same cable. The MA may then analyze the data and build repair packages. An exemplary embodiment of the present invention allows the MA to analyze ALIT data without having to sift through large volumes of paper and without having to be knowledgeable in database search tools (e.g., SQL).

In FIG. 1, a block diagram of an exemplary system for facilitating the analysis of ALIT data is generally shown. The exemplary system includes a host system 110 located in a central office operating as an application server. The host system 110 executes a tool called ALIT and dumps the results to a commercially available tool called Predictor, which compiles morning reports detailing ALIT exceptions. The Predictor tool runs on the predictor system 112. ALIT is performed nightly by equipment that sequentially tests lines in the central office for battery crosses and grounds. The Predictor reports that include the results of all the tests, including good cables and cables with battery crosses and grounds are sent to a printer. In an exemplary embodiment of the present invention, the Predictor reports are printed to a virtual printer and the reports are stored in a storage device 108 connected (directly or via a network) to the host system 110.

The system in FIG. 1 also includes one or more user systems 102 through which MAs located at one or more geographic locations may contact the host system 104 to initiate the execution of the ALIT analysis process. In an exemplary embodiment of the present invention, the host system 104 executes the ALIT analysis application program and the user system 102 is coupled to the host system 104 via a network 106. Each user system 102 may be implemented using a general-purpose computer executing a computer program for carrying out the processes described herein. The user system 102 may be a personal computer (e.g., a lap top, a personal digital assistant) or a host attached terminal. If the user system 102 is a personal computer, the processing described herein may be shared by a user system 102 and the host system 104 (e.g., by providing an applet to the user system 102).

The network 106 may be any type of known network including, but not limited to, a wide area network (WAN), a local area network (LAN), a global network (e.g. Internet), a virtual private network (VPN), and an intranet. The network 106 may be implemented using a wireless network or any kind of physical network implementation known in the art. A user system 102 may be coupled to the host system through multiple networks (e.g., intranet and LAN) so that not all user systems 102 are coupled to the host system 104 through the same network. One or more of the user systems 102 and the host system 104 may be connected to the network 106 in a wireless fashion. In an exemplary embodiment, the user system 102 is connected to the host system 104 via an intranet and the host system 104 executes the ALIT analysis application software.

The storage device 108 may be implemented using a variety of devices for storing electronic information. It is understood that the storage device 108 may be implemented using memory contained in the host system 104 or it may be a separate physical device. The storage device 108 is logically addressable as a consolidated data source across a distributed environment that includes a network 106. The physical data may be located in a variety of geographic locations depending on application and access requirements. Information stored in the storage device 108 may be retrieved and manipulated via the host system 104. The storage device 108 includes an ALIT database. The storage device 108 may also include other kinds of data such as information concerning the creation of the ALIT database records (e.g., date and time of creation). In an exemplary embodiment of the present invention, the host system 104 operates as a database server and coordinates access to application data including data stored on storage device 108.

The host system 104 depicted in FIG. 1 may be implemented using one or more servers operating in response to a computer program stored in a storage medium accessible by the server. The host system 104 may operate as a network server (e.g., a web server) to communicate with the user system 102. The host system 104 handles sending and receiving information to and from the user system 102 and can perform associated tasks. The host system 104 may reside behind a firewall to prevent unauthorized access to the host system 104 and enforce any limitations on authorized access. A firewall may be implemented using conventional hardware and/or software as is known in the art.

The host system 104 may also operate as an application server. The host system 104 executes one or more computer programs to facilitate the analysis of ALIT data. One of the computer programs is the ALIT analysis application program. Processing may be shared by the user system 102 and the host system 104 by providing an application (e.g., java applet) to the user system 102. Alternatively, the user system 102 may include a stand-alone software application for performing a portion or all of the processing described herein. As previously described, it is understood that separate servers may be utilized to implement the network server functions and the application server functions. Alternatively, the network server, the firewall, and the application server may be implemented by a single server executing computer programs to perform the requisite functions.

FIG. 2 is flow diagram of an exemplary process for creating an ALIT database for analyzing ALIT data. At step 202, the ALIT is executed in the central office. At step 204, the ALIT results are transmitted to the Predictor system 112. The Predictor software compiles a morning report for each wire center at step 206. Next, at step 208, the Predictor software transmits the morning report to a virtual printer 208, located on a storage device 108. In this manner, the Predictor software does not need to be modified to utilize an exemplary embodiment of the present invention because the Predictor software sends output to the storage device 108 in the same manner that it already sends output to a printer. At step 210, the software located on the host system 104 parses the text of the Predictor reports (e.g., extracts only exception records) and inserts the data into an ALIT database located on the storage device 108. Finally, at step 220, the MAs may access the data in the ALIT database via a network.

FIG. 3 is an exemplary ALIT database located on the storage device 108 and created by step 210 in FIG. 2. The database includes an entry, or record, for each exception in the Predictor report. Each entry includes attributes such as: wire center 302; maintenance analyst name 304; exception date 306; repair package 308 (blank if no repair package has been built for the exception and filled in with a repair package number if the MA has built a repair package for the exception); facility number 310; cable 312; pair 314 within the cable; trouble message 316; telephone number 318 affected by the exception; terminal address (TEA) 320; and test result 322. In an exemplary embodiment of the present invention, the ALIT database is a relational database to allow for easy sorting, manipulating and reporting of the ALIT data, however other database management systems may be implemented. Alternate embodiments of the present invention may include a subset of these attributes and/or additional attributes depending on installation requirements. In the exemplary embodiment of the ALIT database depicted in FIG. 3, the attributes are sourced from the Predictor reports. In an alternate embodiment of the present invention, attributes from other sources may be combined with the Predictor report database based on installation requirements.

FIG. 4 is a flow diagram of an exemplary process that a MA may follow when utilizing an ALIT database for analyzing ALIT data. At step 402 the MA may view a list that includes the number of exceptions per wire center for a particular day. FIG. 5 is an exemplary user interface screen for viewing a list of the number of exceptions per wire center for a particular day. The user interface screen includes a table with one line for each wire center 302. The columns of the table include: wire center 302; maintenance analyst name 304; maximum packages 502 (the field supervisor's estimate at how many packages his team can handle); total number of exceptions 504 in the wire center 302; and exception date 306. With the exception of the maximum packages 502 column, the information in the user interface screen depicted in FIG. 5 is derived by executing a query against the data contained in the ALIT database.

Referring back to FIG. 4, at step 404, the MA may select a wire center 302 from the user interface screen depicted in FIG. 5 by “clicking on” a particular wire center 302 on the screen. At step 406, a list of all the exceptions for the selected wire center is presented to the MA. FIG. 6 is an exemplary user interface for viewing a list of all exceptions for the selected wire center. The user interface screen includes a table with one line for each exception. The columns of the table include: repair package 308; facility number 310; cable 312; pair 314; trouble message 316; telephone number 318; TEA 320 and test result 322. The user interface screen is also color coded and sorted by cable so that a MA may quickly identify which exceptions belong to the same cable. For example, the first line 602 is an exception for cable number thirteen and the second four lines 604 are exceptions for cable number eleven hundred and forty-four.

The table in FIG. 6 does not include exceptions that have already been addressed (e.g., by building a repair package) by the MA so that the MA can focus on those exceptions that may possibly need to be addressed. In an alternate exemplary embodiment, the table depicted in FIG. 6 only includes cables that have three or more exceptions, and/or the table is sorted with the cables having the highest number of exceptions coming first. Any number of sort orders and selection criteria may be utilized with an exemplary embodiment of the present invention to build the screen depicted in FIG. 6. The sort order and selection criteria for the table may be modified (e.g., for the entire system, for a particular wire center, for a particular MA, for a particular day) as required. To build a repair package for one or more exceptions the MA selects, or “clicks on” the repair package 308 column in the table.

Referring back to FIG. 4, a MA may decide to build a repair package that includes one or more exceptions at step 408. The decision to build a repair package may be based on many factors such as the number of failures and/or the severity of failures for a particular cable. In an exemplary embodiment of the present invention, the MA enters a separate system to build a repair package and then returns to the ALIT analysis application program to enter information about the repair package. FIG. 7 is an exemplary user interface for entering repair package information into the ALIT database. The user interface displays the wire center 302, the facility number 310, the cable 312 and the exception date 306. The user is prompted to enter the number associated with the repair package 308, the low pair 314 included in the repair package 308 and the high pair 314 included in the repair package 308. When the MA selects submit 702 the information is added into the ALIT database. In an alternate exemplary embodiment of the present invention, the system that builds the repair package is integrated with the ALIT analysis system to automatically update the ALIT database with the information when a repair package is built. This may be accomplished by having the ALIT analysis system extract information from the system that builds the repair packages or by having the repair package building system sending the information to the ALIT database.

FIG. 8 is a flow diagram of an exemplary process for analyzing the decision process of a maintenance analyst when a repair package was created. This may be useful in refining the decision process used by the MAs to determine when to create a repair package and to track the types of exceptions that actually require a repair package for correction. At step 802, a MA supervisor or MA may select the report option. At step 804, the MA supervisor is presented with a list of the number of repair packages built per month by each MA. FIG. 9 is an exemplary user interface for viewing a list of the number of repair packages built per month by each MA. The user interface screen in FIG. 9 includes a table with one line for each MA. The MA is identified by a common user identification (CUID) 902 which corresponds to the MA name 304. For each CUID 902 a year to date total 904 of all repair packages built as well as the total number of repair packages built on a monthly basis 906 are displayed. The values in these columns may be calculated using data contained in the ALIT database.

Referring back to FIG. 8, at step 806, the MA supervisor selects a month for a particular MA by “clicking on” the month in the user interface screen depicted in FIG. 9. At step 808, the MA supervisor may view a list of all repair packages built in the selected month for the selected MA. FIG. 10 is an exemplary user interface for viewing a list of all repair packages built in a selected month by a particular MA. The MA supervisor is presented with a table that includes one line for each repair package built during the selected month. The columns include wire center 302, exception date 306, facility number 310, cable 312, low pair 314, high pair 314 and repair package 308. Again, the data in these columns is derived from the contents of the ALIT database.

At step 810 in FIG. 8, the MA supervisor may select a particular repair package to understand the criteria utilized by the MA in creating the repair package by “clicking on” the repair package field in FIG. 10. At step 812, the ALIT test results the MA utilized when deciding to build the repair package are displayed. FIG. 11 is an exemplary user interface for viewing the test data utilized by a MA when the MA decided to build the repair package. The user interface screen includes a table with one line for each exception. The columns of the table include: facility number 310; cable 312; pair 314; trouble message 316; telephone number 318; TEA 320 and test result 322. The user interface screen is also color coded and sorted by cable so that a MA supervisor may quickly identify which exceptions belong to the same cable. For example, the first three lines 1102 are exceptions for cable number one and the next three lines 1104 are exceptions for cable number thirteen.

These reports may be utilized by a MA supervisor for evaluation and training of MAs and they could point out the need for modified criteria for building repair packages. These reports are examples of the type of information that may be gleaned from the ALIT database. Other sort orders and content are possible in an alternate exemplary embodiment of the present invention. In addition, the reports may be entered into a spreadsheet package (e.g., Excel) and/or e-mailed to a field technician if there is some question about whether a repair package should have been created. An alternate embodiment of the present invention includes creating a report that shows the status of ALIT in all offices. The report may filter out only those offices that require attention because ALIT has not executed. In this manner a MA may know whether the data in the ALIT database is complete.

An embodiment of the present invention organizes ALIT exception data in an on-line database. This may lead to increased analysis speed because a MA is no longer required to sift through a massive report to identify and group exceptions to build a repair package. In contrast, an embodiment of the present invention groups together exceptions based on exception date and cable so that the MA may easily identify and analyze exceptions. In addition, using an automated on-line database may lead to a decrease in the number of errors in terms of repair packages that weren't built that should have been built and repair packages that were built that didn't need to be built. This may lead to an increased reliance by technicians in the field on the repair packages being built and delivered. Further, the ability to analyze the data that a MA had available on a particular date may lead to improving the repair package building analysis process. An embodiment of the present invention may also lead to a cost savings in terms of the amount of paper that may be saved. Finally, a value may be attached to fixing exceptions more quickly in terms of both MA time savings and customer good will.

As described above, the embodiments of the invention may be embodied in the form of computer-implemented processes and apparatuses for practicing those processes. Embodiments of the invention may also be embodied in the form of computer program code containing instructions embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other computer-readable storage medium, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes an apparatus for practicing the invention. An embodiment of the present invention can also be embodied in the form of computer program code, for example, whether stored in a storage medium, loaded into and/or executed by a computer, or transmitted over some transmission medium, such as over electrical wiring or cabling, through fiber optics, or via electromagnetic radiation, wherein, when the computer program code is loaded into and executed by a computer, the computer becomes an apparatus for practicing the invention. When implemented on a general-purpose microprocessor, the computer program code segments configure the microprocessor to create specific logic circuits.
